automatic greenhouse vent

The Automatic Vent Opener was made to automatically control the temperature and humidity amounts and offer additional ventilation when needed, making gardening easier. As the surroundings within the greenhouse warms, the vent gradually opens to enable the correct amount of air flow into the greenhouse and closes when the temperature cools. The vent arm was made with a steel cylinder that contains wax which expands when heated to press a piston, which raises the window, as the air flow gets warmer, then contracts since it cools, closing with the use of a springtime and resetting the piston. All you need to do can be to install it on your own roof vent screen and it automatically starts operating. The Automatic Vent Opener functions without the utilization of electricity and is compatible with all Palram greenhouse versions only. The solar powered Vent Opener will start to open as temperature ranges inside your greenhouse reach 68 Automatic Greenhouse Vent degrees F with full-open at 80 degrees. It installs efficiently and can provide care-free ventilation.
